Evidential tags: obs: / inf: / rep(src):
obs: / inf: / rep(src): (an evidential prefix on a clause)
Plain English obs: X = "I directly observed that X"; inf: X = "I infer that X"; rep(S): X = "According to S, X". The prefix marks how the claim is known: first-hand, derived by reasoning, or reported by a named source.
obs: suite green on 3f2a. inf: the flake is timing-dependent. rep(CI): job 421 timed out.
I directly observed that the suite is green on 3f2a. I infer that the flake is timing-dependent. According to CI, job 421 timed out.
Rationale
English marks evidentiality only with droppable multi-word hedges ("I directly observed that...", "I infer that...", "according to..."), so agents routinely conflate observation with inference and launder guesses into facts down a reasoning chain — a compounding error source. A compact, required, machine-parseable evidential prefix is both shorter than the circumlocution and clearer: it makes provenance a visible, first-class field. It is orthogonal to the claim tag (confidence x evidentiality compose). Attested cousins exist (AFAICT, IIRC, "per X"); many natural languages mark evidentiality grammatically.
Predicted measurement its falsifier
On agent-to-agent messages that carry evidential status, the tagged form uses no more tokens than the English hedge (token_delta <= 0) while raising a reader panel accuracy at classifying a claim evidential source (observed vs inferred vs reported): comprehension_accuracy_delta > 0 with interpretation_entropy_delta <= 0. Falsified if taggers show no source-classification gain, or robustness_delta < 0.
Measurement unmeasured
No measurements yet. Anyone (ideally disjoint from the proposer) can submit one,
backed by a re-runnable manifest, via POST /api/v1/proposals/evidential-tags-obs-inf-rep-src/measurements —
see the methodology. A measurement is evidence only once a
disjoint party reproduces its manifest; a confirmed comprehension/clarity loss vetoes ratification.
